T0 at whom it may concern.-

Be it known that I, MELVIN D. KILMER, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Spring-Seats to be Used for Chairs, Sofas, Wagon-Seats, 850. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in spring-seats to be used for chairs, sofas, wagon-seats, &c.

The invention consists in the construction hereinafter set forth.

In the drawings, Figure 1 represents a transverse section of a spring-seat of a chair provided with the invention. Fig. 2 represents an enlarged detail view showing a spring secured to the supporting-wire. Figs. 3 and 4 show side and end views of the clamp for holding the springs to the supporting-Wire. Figs. 5 and 6 show a modified form of clamp. Fig. 7 shows a modified form for the attachment of the supporting-rod to the chair-frame different from that shown in Fig. 1.

In the annexed drawings the letter A indicat-es a chair provided with a spring-seat B, having the frame I). Extending across the seat-frame are Wires or rods 0, having the body portion a and the ends 0. These ends 0 are turned upwardly and outwardly and then downwardly, terminating in the points 0 which are firmly secured in the opposite ends of the frame 17.

The letter D represents spiral springs of ordinary construction, the lower ends (1 of which are secured to the rods 0 by means of a clamp E. This clamp E consists of the two lips 6, there being in each lip the transverse opening 2. This transverse opening a is made elongated and having at one end the opening enlarged, as at c of larger size than the diameter of the end (1 of the spring D. The other end e of the elongated opening 6 is somewhat smaller than the diameter of the end (1 of the spring D. The clamp E is placed about the rod 0, so as to curve around or straddle it, as shown in the drawings. This brings the two transverse elongated openings 6 opposite each other and lengthwise of the rod 0. When at the proper position on the rod 0, the clamp E is forced against the rod 0 and clamped in place. The end (Z of the spring D is then passed through the registering ends (2 of the elongated slots or openings 6 and then is forced or jammed down into the ends a the difference in size of these ends and the end at causing the latter to be held firmly in place.

In Figs. 5 and 6 is shown a modification of the clamp. Here the clamp e is provided with elongated notches e having the open ends 6 This clamp e is slipped upon a rod 0 and held in the same way as is the clamp E. The end (1 of the spring D is slipped into the notches e, and then the clamp is squeezed together, as shown in Fig. 6, whereby the spring is securely held to the rod.

In both forms of clamps the elongated openings are lengthwise of the rod 0 and transverse the end d of the spring D. This formation of the clamp permits it to be readily clamped upon the rod 0, and also the end of the spring is placed in the openings, forced sidewise into place, and thus jammed down into the bottom of the elongated openings.

In Fig. 7 the end of the rod 0' of the rod 0 is held to the end 01 of the chair-frame by being hooked into an eye f.

With a device such as described the springs are securely clamped to the supporting-rods and held against displacement. As many springs may be used as desired, and they may be placed along the rod and spaced apart any suitable distances. By using a clamp such as described any amount of adjustment of the springs along the rod maybe made. At the same time there is not required any definite accuracy of position, as the springs may be put at any place along the rod and be clamped into position. With such a device the springs may be readily and rapidly put in place by any competent Workman, as no nice adjustment is required. Should it be desired to remove a spring, the clamp can be quickly released, the spring withdrawn, and a new one be replaced.

Having described my invention, what I claim is- 1. In a spring-seat, the combination of the seat-frame, transverse rods, the springs, and the clamps for holding the springs to the rods,

IOO

such clamps having elongated openings and the ends of the springs resting in said openings, the latter being lengthwise the rods and transverse the ends of the springs as set forth.

2. In a spring-seat, the combination of the spring-supporting rod, the springs, and the clamps, E, having elongated openings, 6', the ends of the springs resting in said openings, one end of said openings, 6', being larger and the other end'of said openings being smaller to than the diameter of the wire forming the springs, as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
